##### 1: 19.15 Advantages of Symmetry

…
►Symmetry in $x,y,z$ of ${R}_{F}(x,y,z)$, ${R}_{G}(x,y,z)$, and ${R}_{J}(x,y,z,p)$
replaces the five transformations (19.7.2), (19.7.4)–(19.7.7) of Legendre’s integrals; compare (19.25.17).

$$\mathrm{\Pi}(\varphi ,{\alpha}^{2},k)=-\frac{1}{3}{\omega}^{2}{R}_{J}(c-1,c-{k}^{2},c,c-{\omega}^{2})+\sqrt{\frac{(c-1)(c-{k}^{2})}{({\alpha}^{2}-1)(1-{\omega}^{2})}}{R}_{C}(c({\alpha}^{2}-1)(1-{\omega}^{2}),({\alpha}^{2}-c)(c-{\omega}^{2})),$$
${\omega}^{2}={k}^{2}/{\alpha}^{2}$.

##### 4: Bille C. Carlson

…
►The main theme of Carlson’s mathematical research has been to expose previously hidden permutation symmetries that can eliminate a set of transformations and thereby replace many formulas by a few.

The text “greatest common divisor of $m,n$” was replaced with “greatest common divisor of $k,m$”.

This figure was rescaled, with symmetry lines added, to make evident the symmetry due to the inverse relationship between the two functions.
